<![CDATA[The cigarette packer machine serves as a primary unit in the manufacturing process to perform automatic, fast, and continuous packaging. General Background Optimal packer machine performance plays a vital role in maintaining production continuity, packaging quality, and achieving company targets. Specific Background The cigarette packer machine at PT. XX frequently experiences failures that lead to increased downtime, reduced production output, and decreased operational efficiency. Knowledge Gap Existing operational practices require a systematic analysis to determine root failure causes and evaluate comprehensive corrective and preventive maintenance measures. Aims This study aims to identify failure types, analyze root causes using the fishbone method, evaluate Overall Equipment Effectiveness (OEE), and review corrective and preventive measures implemented by the company. Results Findings indicate that machine failures are dominantly caused by mechanical wear, electrical disturbances, and human errors, resulting in an OEE value of 72.4 percent. Novelty This work establishes an integrated evaluation framework combining failure frequency analysis, fishbone root-cause identification, and OEE performance metrics for cigarette packaging lines. Implications Implementing scheduled preventive maintenance and improving work environmental conditions significantly minimize downtime and improve overall manufacturing productivity. Key Findings Highlights Mechanical component wear resulting from continuous operation constitutes the most dominant failure category at forty-five percent of total occurrences. Control system failures generate the highest average downtime per incident due to complex diagnosis requirements. The calculated Overall Equipment Effectiveness value of seventy-two point four percent remains below ideal manufacturing industry standards.
